4 Function and system design Measuring principle The Levelflex is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point (process connection of the measuring device ä 44) to the product surface is measured. High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by the product surface, received by the electronic evaluation unit and converted into level information. This method is also known as TDR (Time Domain Reflectometry). flange: reference point of measurement 20 ma 100% D probe length LN F E L 4mA 0% Reference point of the measurement, details ä 44 L00-FMP4xxxx en-002 Dielectric constant The dielectric constant (DK) of the medium has a direct impact on the degree of reflection of the highfrequency pulses. In the case of large DK values, such as for water or ammonia, there is strong pulse reflection while, with low DK values, such as for hydrocarbons, weak pulse reflection is experienced. Input The reflected pulses are transmitted from the probe to the electronics. There, a microprocessor analyzes the signals and identifies the level echo which was generated by the reflection of the high-frequency pulses at the product surface. This clear signal detection system benefits from over 30 years' experience with pulse time-offlight procedures that have been integrated into the development of the PulseMaster software. The distance D to the product surface is proportional to the time of flight t of the impulse: D = c t/2, where c is the speed of light. Based on the known empty distance E, the level L is calculated: L = E D Reference point for "E" see diagram above. The Levelflex possesses functions for interference echo suppression that can be activated by the user. They guarantee that interference echoes from e.g. internals and struts are not interpreted as level echoes. 4 Endress+Hauser

5 Interface measurement When the high-frequency pulses hit the surface of the medium, only a percentage of the transmission pulse is reflected. In the case of media with a low DK 1, in particular, the other part penetrates the medium. The pulse is reflected once more at the interface point to a second medium with a higher DK 2. The distance to the interface layer now can also be determined taking into account the delayed time-of-flight of the pulse through the upper medium. c = c = km/s 0 total level C 0 DK 1 C 1 = DK 1 interface level DK 2 L00-FMP4xxxx en-007 Output The Levelflex is preset at the factory to the probe length ordered so that in most cases only the application parameters that automatically adapt the device to the measuring conditions need to be entered. For models with a current output, the factory adjustment for zero point E and span F is 4 ma and 20 ma, for digital outputs and the display module 0 % and 100 %. A linearization function with max. 32 points, which is based on a table entered manually or semi-automatically, can be activated on site or via remote operation. This function allows the level to be converted into units of volume or mass, for example. Endress+Hauser 5

9 Integration into the tank gauging system The Endress+Hauser Tank Side Monitor NRF590 provides integrated communications for sites with multiple tanks, each with one or more sensors on the tank, such as radar, spot or average temperature, capacitive probe for water detection and/or pressure sensors. Multiple protocols out of the Tank Side Monitor guarantee connectivity to nearly any of the existing industry standard tank gauging protocols. Optional connectivity of analog 4 to 20 ma sensors, digital I/O and analog output simplify full tank sensor integration. Use of the proven concept of the intrinsically safe HART bus for all on-tank sensors yields extremely low wiring costs, while at the same time providing maximum safety, reliability and data availability.

For their part, the Fieldgates monitor the configured level limits and, if required, automatically activate the next supply. The spectrum of options here ranges from a simple purchasing requisition via through to fully automatic order administration by coupling XML data into the planning systems on both sides. Remote maintenance of measuring equipment Fieldgates not only transfer the current measured values, they also alert the responsible standby personnel, if required, via or SMS. In the event of an alarm or also when performing routine checks, service technicians can diagnose and configure connected HART devices remotely. All that is required for this is the corresponding HART operating software (e.g. FieldCare, etc.) for the connected device. Fieldgate passes on the information transparently, so that all options for the respective operating software are available remotely. Some onsite service operations can be avoided by using remote diagnosis and remote configuration and all others can at least be better planned and prepared. via HART Client: - FieldCare...

21 Operating conditions: installation with level measurement General information on level measurement Probe selection (see overview on ä 6-7) Normally, rope probes should be used for bulk solids, rod probes are only suitable for short measuring ranges up to approx. 2 m in bulk solids. This applies above all to applications in which the probe is installed laterally at an angle and for light and pourable bulk solids. Normally use rod or coax probes for liquids. Rope probes are used in liquids for measuring ranges > 4m and with restricted ceiling clearance which does not allow the installation of rigid probes. Coax probes are suited to liquids with viscosities of up to approx. 500 cst. Coax probes can measure most liquefied gases, as of a dielectric constant of 1.4. Moreover, installation conditions, such as nozzles, tank internal fittings etc., have no effect on the measurement when a coax probe is used. A coax probe offers maximum EMC safety when used in plastic tanks. In the case of large silos, the lateral pressure on the rope can be so high that a rope with plastic jacketing must be used. We recommend PA-coated ropes be used for cereal products wheat, flour etc.. Mounting location Do not mount rod or rope probes in the filling curtain (2) Mount rod and rope probes away from the wall (B) 1 2 at such a distance that, in the event of buildup on the wall, there is still a minimum distance of 100 mm between the probe and the buildup. Mount rod and rope probes as far away as possible from installed fittings. "Mapping " must be carried out during commissioning in the event of distances < 300 mm. When installing rod and rope probes in plastic B containers, the minimum distance of 300 mm also applies to metallic parts outside the container. Rod and rope probes may not, at times, contact metallic container walls or floors. Minimum distance of probe end to the container floor (C): Rope probe: 150 mm Rod probe: 50 mm Coax probe: 10 mm C When installing outdoors, it is recommended that you use a protective cover (1) see "Accessories" on ä 58. Avoid buckling the rope probe during installation or operation (e.g. through product movement against silo wall) by selecting a suitable mounting location. L00-FMP4xxxx xx-003 Endress+Hauser 21

22 Other installations Select the mounting location such that the distance to internals (5) (e.g. limit switch, struts) > is 300 mm over the entire length of the probe, also during operation. Probe must within the measuring span not touch any internals during operation. If necessary, when using rope probes the probe end (4) may be fixed to secure it ( ä 24)!. Optimization options Interference echo suppression: measurement can be optimized by electronically tuning out interference echoes. 5 4 L00-FMP4xxxx xx-008 Type of probe installation Probes are mounted to the process connection with threaded connections or flanges and are usually also secured with these. If during this installation there is the danger that the probe end moves so much that it touches the tank floor or cone at times, the probe must, if necessary, be shortened and fixed down. The easiest way to fix the rope probes is to screw them to the internal thread on the lower end of the weight. Thread size, ä 24. The ideal installation is mounting in a screwed joint / screw-in sleeve which is internally flush with the container ceiling. If installation takes place in a nozzle, the nozzle should be 50 to 150 mm in diameter and should not be more than 150 mm high. Installation adapters are available for other dimensions, ä 35. installation with welding boss installation in nozzle < 150 mm ( < 4") diameter nozzle: < DN150 ( < 6 ) L00-FMP4xxxx en-017 " Caution! Welding the probe into the vessel Before welding the probe into the vessel, it must be grounded by a low-resistive connection. If this is not possible, the electronics as well as the HF module must be disconnected. Otherwise the electronics may be damaged. 22 Endress+Hauser

23 Special notes for bulk solids In the case of bulk solids, as great a distance as possible from the filling curtain is especially important to avoid wear. In concrete silos, a large distance (B) should be observed between the probe and the concrete wall, if possible 1 m, but at least 0.5 m. The installation of rope probes must be carried out carefully. The rope should not be buckled. If possible, installation should be carried out when the silo is empty. Check the probe regularly for defect. B L00-FMP4xxxx xx-005 Installation in concrete silos Installation, for example, into a thick concrete ceiling should be made flush with the lower edge. Alternatively, the probe can also be installed into a pipe that must not protrude over the lower edge of the silo ceiling. The pipe should kept at a minimum length. Installation suggestions see diagram. ³ 100 mm ³ 100 mm metal metal tube Ø mm Extension rod / Centering (see accessories) L00-FMP4xxxx en-008 Note for installations with rod extension/center washer (accesories): Strong dust generation can lead to build-up behind the center washer. This can cause an interference signal. For other installation possibilities please contact Endress+Hauser. Endress+Hauser 23

24 Fixing rope probe The end of the probe needs to be secured if the probe would otherwise touch the silo wall, the cone or another part, or the probe comes closer than 0.5 m to a concrete wall. This is what the internal thread in the probe weight is intended for: for 4 mm rope: M14 for 6 mm rope: M20 Preferably use the 6 mm rope probe due to the higher tensile strength when fixing a rope probe ä 58The fixing must be either reliably grounded or reliably insulated (see accessories on Accessories). If it is not possible to mount the probe weight with a safe earthed connection, it can be secured using an isolated eyelet, which is available as an accessory ( ä 61). In order to prevent an extremely high tensile load and the risk of rope crack, the rope has to be slack. Make the rope longer than the required measuring range such that there is a sag in the middle of the rope that is 1 cm/m of the rope length. sag of the rope: 1cm/m of the rope length L00-FMP4xxxx en-019 Reliable, earthed mounting Reliable, isolated mounting Mounting-kit isolated (see accessories) Mounting and contact with a bolt 4mm-rope: M14 6mm-rope: M20 L00-FMP4xxxx en Endress+Hauser

25 Installation from the side If installation from above is not possible, the Levelflex can also be mounted from the side. In this case, always fix the rope probe (see Fixing rope probe). Support rod and coax probe if the lateral loadbearing capacity is exceeded (see table, ä 6-7). Only fix rod probes at the probe end. Caution! Remove or ground the electronics when welding the sleeve as the device will otherwise be destroyed! Ø16mm Ø <26 mm Ø mm L00-FMP4xxxx en-035 Endress+Hauser 25

26 Tensile load Bulk solids exert tensile forces (maximum admissible values ä 6-7) on rope probes whose height increases with: the length of the probe, i.e. max. cover, the bulk density of the product, the silo diameter and the diameter of the probe rope The following diagrams show typical loads for frequently occurring bulk solids as reference values. The calculation is performed for the following conditions: Suspended probe (probe end not fixed at the bottom) Free-flowing bulk solid, i.e. mass flow. A calculation for core flow is not possible. In the event of collapsing cornices, considerably higher loads can occur. The specification for tensile forces contains the safety factor 2, which compensates for the normal fluctuation range in pourable bulk solids silica sand smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m polyethylene pellets smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m tensile force, 6 mm rope [kn] tensile force, 4 mm rope [kn] tensile force, 6 mm rope [kn] tensile force, 4 mm rope [kn] level [m] level [m] L00-FMP40xxx en-007 L00-FMP40xxx en-008 tensile force, 6 mm rope [kn] wheat smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m tensile force, 4 mm rope [kn] tensile force, 6 mm rope [kn] cement smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m tensile force, 4 mm rope [kn] level [m] level [m] L00-FMP40xxx en-006 L00-FMP40xxx en Endress+Hauser

27 Since the tensile forces are also heavily dependent on the viscosity of the product, a higher safety factor is necessary for highly viscous products and if there is a risk of cornice buildup. In critical cases it is better to use a 6 mm rope instead of a 4 mm one. The same forces also act on the silo cover. On a fixed rope, the tensile forces are definitely greater, but this can not be calculated. Observe the tensile strength of the probes or ensure that the tensile strength of the probes is not exceeded (see table, ä 6-7). Options for reducing the tensile forces: Shorten the probe. If the maximum tensile load is exceeded, check whether it would be possible to use a non-contact Ultrasonic or Level-Radar device. Special notes for liquids When installing in agitation units, check whether a no-contact process (Ultrasonic or Level-Radar) would be better suited, especially if the agitator generates large mechanical loads on the probe. If Levelflex is, nevertheless, installed in tanks with agitators, it is better to use coax probes which have a greater lateral loading capacity, ä 6-7. Additionally the coax probe can be protected against warping. ä 30. Standard installation Using a coax probe offers great advantages when the viscosity of the product is < 500 cst and it is certain that the product does not accumulate buildup: Greater reliability: As of dielectric constant=1.4, measurement functions independently of all electrical properties in all liquids. Internals in the tank and nozzle dimensions do not have any influence on measurement. Higher lateral load-bearing capacity than rod probes. For higher viscosity a rod probe is recommended, or using a non-contact measuring principle with the Level- Radar Micropilot M. Installation in horizontal and upright cylindrical tanks Use a coax or rod probe for measuring ranges up to 4 m. For longer measuring ranges, a separable probe is available as special version, or the use of a 4 mm rope probe is recommended. Installation and possible fixing as with bulk solids. Any distance from wall, as long as occasional contact is prevented. When installing in tanks with a lot of internals or internals situated close to the probe: use a coax probe. 1 2 L00-FMP4xxxx yy-021 Endress+Hauser 27

28 Installation in underground tanks Use coax probe for nozzles with large diameters in order to avoid reflections at the nozzle wall. L00-FMP4xxxx yy-022 Measurement in corrosive liquids For measurement in corrosive liquids use Levelflex M FMP41C. When using plastic tanks it is also possible to mount the probe on the outside of the tank (see installation instructions on ä 29). Levelflex measures the level of aqueous media through the plastic. Installation in stilling well or bypass A rod probe can be used for pipe diameters bigger than 40 mm. When installing a rod probe into a metallic pipe with internal diameter of up to 150 mm, you have all the advantages of a coax probe. Welded joints that protrude up to approx. 5 mm inwards do not influence measurement. L00-FMP4xxxx yy Endress+Hauser

29 Installation in plastic containers Please note that the "guided level radar" measuring principle requires a metallic surface at the process connection! When installing the rod and rope probes in plastic silos, whose silo cover is also made of plastic or silos with wood cover, the probes must either be mounted in a DN50 / 2" metallic flange, or a metal sheet with diameter of 200 mm must be mounted under the screw-in piece. metal sheet or metal flange silo roof of plastic or wood metal sheet or metal flange Wall thickness for GFK/PP <15mm L00-FMP4xxxx en-018 It is also possible to mount the probe externally on the tank wall for measuring in Aqueous solutions. Measurement then takes place through the tank wall without contacting the medium. If people are in the vicinity of the probe mounting location, a plastic half pipe with a diameter of approx. 200 mm, or some other protective unit, must be affixed externally to the probe to prevent any influences on the measurement. There must not be any metallic reinforcement rings secured to the tank. The wall thickness should be < 15 mm for at GFR/PP. There must be no open space between the tank wall and the probe.

The DK of the upper medium may not be greater than 10. The DK difference between the upper medium and lower medium must be >10. The interface must have a minimum thickness of 60 mm (interface electronics version) or 100 mm (special version). Emulsion layers in the vicinity of the interface can severely dampen the signal. However, emulsion layers up to 50 mm are permitted. Endress+Hauser 31

32 Interface electronics version: The device with the "Interface" electronics version makes it possible to measure the total level and the interface level simultaneously.

33 Probe selection (see overview on ä 6-7) For interface measurement, ideally coax probes or rod probes are used in the bypass/stilling well. Coax probes are suited to liquids with viscosities of up to approx. 500 cst. Coax probes can measure most liquefied gases, as of a dielectric constant of 1.4. Moreover, installation conditions, such as nozzles, tank internal fittings etc., have no effect on the measurement when a coax probe is used. A coax probe offers maximum EMC safety when used in plastic tanks. Rod or rope probes for free installation in the tank available on request. Rope probes for free installation in the tank must always be used with a rod weight in accordance with special products MVTFN0203 or MVT6N0186. Rope probes may not be used in the bypass/stilling well since the end weight always causes interference reflection which can be misinterpreted during interface measurement. Special information on interface measurement Installation in horizontal cylindrical, upright and underground tanks Use coax probes or rod probes in the bypass/stilling well. A separable probe is available as a special version for longer measuring ranges. Any distance from the wall is possible for coax probes or rod probes in the stilling well. In the case of rod probes, it must be ensured that the probe does not come into contact with the wall. L00-FMP4xIxx xx-002 Installation in stilling well or bypass A rod probe can be used for pipe diameters bigger than 40 mm. Rod probe installation can take place up to a diameter size of 100 mm. In the event of larger diameters, a coax probe is recommended. Welded joints that protrude up to approx. 5 mm inwards do not influence measurement. The pipe may not exhibit any steps in diameter. In the case of rod probes, it must be ensured that the probe does not come into contact with the wall. If necessary, use a centering disk at the end of the probe.! Note! A plastic centering disk has to be used for interface measurement (see Accessories ä 60). L00-FMP4xIxx xx-003 Endress+Hauser 33

35 Operating conditions: general installation instructions for special installation situations Probe length The measuring range is directly dependent on the probe length. It is better to order probes too long than too short since it is possible to shorten the probe if necessary. In the case of the rope probe with a rod weight, shortening at the probe end weight is only possible with the special product in accordance with MVTFN0186. See also modification information MI0079. Installation in nozzles >150mm high If, when installing probes in nozzles DN40 to 250 / 1½" to 10" with nozzle height (HS) of > 150 mm/6", the probe could touch the lower edge of the nozzle due to moving materials in the container, we recommend using an extension rod with or without centering disk. This accessory consists of the extension rod corresponding to the nozzle height, on which a centering disk is also mounted if the nozzles are narrow or when working in bulk solids. This component is delivered separately from the device. Please order the probe length correspondingly shorter. For the exact length of the rod see "extension rod/centering" on ä 59. Order codes for specific nozzle nominal diameters and heights can be found on ä 59. Only use centering disks with small diameters (DN40 and DN50) if there is no significant buildup in the nozzle above the disk. The nozzle must not become clogged with product. nozzle height Keep metal tube at minimum length! # DN 50 (2") DN 80 (3") DN 150 (6") DN 200 (8") DN 250 (10") centering disk at PPS - GF40 Extension rod Not for ¾" probe.

37 Installation at an angle For mechanical reasons, the probe should be installed as vertically as possible. Installation with a deviation up to approx. 5 from the vertical axis is permitted for probes up to approx. 1 m in length.

39 Replacing a displacer system in an existing displacer chamber The Levelflex M is a perfect replacement for a conventional displacer system in an existing displacer chamber. In addition to the DIN and ANSI flanges, which are available as standard, Endress+Hauser also offers flanges that suit Fischer and Masoneilan displacer chamber (special product) for this purpose. Thanks to menu-guided local operation, commissioning the Levelflex M only takes a few minutes. Replacement is also possible when partially filled, and wet calibration is not required. Your benefits: No moving parts, thus zero-maintenance operation. Not sensitive to process influences such as temperature, density, turbulence and vibrations. The rod probes can be shortened or replaced easily. In this way, the probe can be easily adjusted on site. displacer chamber flange L00-FMP4xIxx en-002! Note! Planning instructions: In normal cases, use a rod probe. When installing into a metallic displacer chamber up to 150 mm, you have all the advantages of a coax probe (see probe selection ä 6-7). It must be ensured that the probe does not come into contact with the side wall. Where necessary, use a centering disk at the lower end of the probe (special product). A centering disk must be adapted as accurately as possible to the internal diameter of the displacer chamber to also ensure perfect operation in the area of the probe end. Additional information on interface measurement The pipe may not exhibit any steps in diameter. Use the coax probe where necessary. In the case of rod probes, it must be ensured that the probe does not come into contact with the wall. If necessary, use a centering disk at the end of the probe.

DIN EN / IEC : 20 to 2000 Hz, 1 (m/s 2 ) 2 /Hz Depending on the application, contamination or buildup can accumulate on the probe. A thin, even layer only influences measurement slightly. Thick layers can dampen the signal and then reduce the measuring range. Severe, uneven buildup, adhesion e.g. through crystallization, can lead to incorrect measurement. In this case, we recommend that you use a non-contact measuring principle, or check the probe regularly for soiling. Electromagnetic compatibility to EN and NAMUR Recommendation EMC (NE21). Details are provided in the Declaration of Conformity. A standard installation cable is sufficient if only the analog signal is used.
